## Discrepancy

(CAN) DURING ENGINE INSPECTION USING A VIDEO BORESCOPE, THE HIGH PRESSURE BLEED VALVE TUBE FROM P3 WAS FOUND CRACKED OFF AND A HORIZONTAL CRACK APPROXIMATELY 3 INCHES LONG BELOW BLEED VALVE ATTACH FLANGE WAS NOTED. SOME STAINING INDICATED CRACK WAS PROBABLY NOT RECENT AND THIS AREA IS NOT READILY VISIBLE WITH THE BLEED VALVE SHROUDS INSTALLED. ALL ENGINE PERFORMANCE RUNS AND TREND MONITORING DATA WERE WITHIN ALLOWABLE PARAMETERS. GAS GENERATOR WAS REMOVED AND SHIPPED FOR REPAIR.
